SNOW- PLOW.

SPECIFICATION t'orming part of Letters Patent No. 351,161, dated October 19, 1886.

Application filed July l, 1886. Serial No. 206,821.

To aZZ whom it may concern:

Be it known that I, RICHARD CAMPBELL, a citizen of the United States of America, residing at Spirit Lake, in the county of Dickinson and State of Iowa, have invented certain new and useful Improvements in Snow-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in snow-plows for railways; and it consists more especially in the construction and combination of the parts, whereby the snow may be readily removed from the tracks, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings,which illustrate my invention, Figure l is a side view of a snow-plow constructed in accordance with my improvement. Fig. 2 is a longitudinal sectional view. Fig. 3 is a front view, and Figs. 4 and 5 are detail views.

A refers to a truck,upon which is mounted a body or car, 13, said car having the front end inclined upwardly, as shown at a, from which inclined front portion a transverse plate, 1), depends, which will lie at a slight distance above the tracks. The body portion of the car is constructed of rigid material, and is thoroughly braced, and is of sufficient weight to prevent the same being readily moved from the tracks. The sides of the car or body B are provided with upwardly-projecting side pieces, B, which serve as supports for a rotary flanged wheel, 0, which is driven by suitable gearing, as will be hereinafter set forth. The inner side of the car is provided with suitable bearings for the support of shafts,which carry the snow-removing devices which are attached to the car-body.

D refers to a shaft which is mounted on bearings (Z 0?, said shaft having a pinion, D. This shaft D is driven from any suitable motor, as an engine, which can be carried, if desired,by the car B. The pinion D engages with the pinion E, which is securely attached to the in (No model.)

ner end of a horizontal shaft, F, which projects through the car-body in front and through the inclined front portion, a, thereof, and to the end of said shaft a propeller-blade or similar device, G, is rigidly secured.

The shaft F at suitable intervals is provided with beveled cog-wheels f and f, the beveled cog-wheels f being adapted to engage with a similar cog-wheel, h, attached to the lower end of a vertical shaft, H. This vertical shaft projects through the top ofthe car, andhas rigidly keyed thereon a conical or pyramidical snowremoving device, H,which,when rotated rapidly, is adapted to throw the snow which may be carried thereto to one side.

The pinion f, attached to the shaft F,engages with a pinion, 2', attached to a transverse shaft, 1, which carries at its outer end a pinion, i, said pinion meshing with the gear-wheel J, which is journaled to one side of the car-body and in a suitable strap-bearing, said gearwheel meshing with the pinion g, which is attached to the end of the shaft which carries the revolving wheel 0, which is provided with blades 0, as shown.

The rotary devices or propeller-blade G, as shown in Fig. 5, is provided with suitable braces, which extend from the forward outer edges of the same to the end of the shaft F, where they are secured by means of a suitable bolt.

The operation of my invention is as follows: The snow is loosened by the propeller-blade G, and as the car is pushed forward it is carried upon the inclined portion a by the scoop or shovel b, and is fed rearwardly by the rotary wheel 0, which turns in the direction indicated by the arrow in Fig. 2. The snow then strikes against the flanged wheel H, and is thrown to one side of the track. In deep snow the propeller-blade G will loosen the same when it is packed, so that the car can work its way through snow-drifts.

I claim- 1. The combination, in a snow-plow constructed substantially as described, of the car or truck having its front portion inclined, a scoop or shovel extending from said inclined portion over the tracks, a shaft, F, having a propeller-blade attached thereto, and a horizontally-flanged wheellocated above said shaft and adapted to carry the snow in contact with attached to a' vertical shaft which projects a vertically -flanged wheel, substantially as through the top of the car, the shafts being shown, and for the purpose set forth. geared to each other, substantially as shown. 15
